- Speed And Science ® designed Big Bore (3-5/8″) Billet Aluminum Shovelhead Cylinders
- Suitable for all ’66-’84 models, this product requires engine cases to be bored out to 3.880″ in order to accept the cylinder spigots.

- Longer stroke requires using stroker plates (not supplied). Shorter strokes (4-1/4 and 4-1/2) require base trimming
- Comes with pressed-in, cetrifugally spun Grey Iron liners, undersized by -.030″ to allow for bore / hone to fit customer’s pistons
- Liner’s beefy, 1/8″ wall thickness allow for up to +.060″ possible overbore.
- Liners are replaceable, making the product infinitely rebuildable.
- Internal, “hidden” oil drains, OEM locations top / bottom
- 9.2lb weight savings (p. pair) versus the all cast-iron construction.
- Much better heat conductivity / dissipation drops the operating temperature up to 50
